ABSTRACT:
The coil (1) of the motor includes a coil body carrying two flanges (7, 8). Made in one piece with one of the flanges (8), a plate (10) covers a lug (4) of the core. This plate (10) acts as anchoring point for the output wires (11, 12) of a wire winding (9) by embedding of the end zones (13, 14) of each of said wires in the plate. Prior to reaching the end zones (13, 14), the wires (11, 12) follow a channel (15) made in the plate, a hole (16, 17) arranged perpendicular to the wires and ending in this channel, being made both in the plate and in the lug.
